A face milling cutter having indexable inserts located in corner pockets at the periphery of the cutting face of the cutter body angularly positioned to provide a cutting edge extending from a point of maximum cutting depth in a direction progressively outward from the axis of rotation, progressively backward relative to direction of rotation and of progressively reduced cutting depth totalling a minor fraction of the outward extension, together with a secondary wiping cutting edge extending from the cutting point inwardly and backwardly relative to the axis and direction of rotation and substantially in the cutting plane of rotation thus providing effective cutting and wiping action in angularly related cutting edges of the same insert. |
